Is y = 1 a solution to the equation 5 + 3y = 8?

Answers

Answer 1

Answer: Yes. It is a solution

Answer 2

Answer: Yes, because 3 times 1 is 3, and 3 plus 5 is 8. 8 is equal to 8. So yes. y=1 is a correct solution to the equation.

a flower bed is in the shape of a triangle with one side twice the length of the shortest side and the third side is 23 feet more than the length of the shortest side. Find the dimensions if the perimeter is 139 feet

Answers

Let the short side be x

One side = 2x

And the third side = x+23

x+2x+x+23=139

4x=116

x=4

The other side = 5

The third side= 27

253+98 then subtract 27

you would do 253-98=155 which equals red , then 155-27=128 which equals blue , the you know that there are 253 yellow , lastly you would do 253+155+128=536 gum balls in the machine

How do I do this problem?

Answers

Answer:

Kate finished the race in 52 seconds

Alexia finished the race in 58 seconds

Trina finished the race in 49 seconds

Step-by-step explanation:

From this work problem we can set up these series of equations:

$k+a+t=159\na=k+6\nt=k-3$

First we need to create only one variable in the first equation in order to solve it, so we can substitute in the other equations into the first one. That would look like this

$k+(k+6)+(k-3)=159$

Then we can simplify this

$3k +3=159\n3k=156\nk=52$

Now that we solve for Kate's time, we can use the other 2 equations to find the times of Alexia and Trina

Using the equation for Alexia's time and plugging in Kate's time gives us

$a=52+6\na=58$

Using the equation for Trina's time and plugging in Kate's time give us

$t=52-3\nt=49$

Two sides of a right triangle have lenghts of 72 cm and 97 cm.the third side is not the hypotenuse.how long is the third base?

Answers

Whenever someone says right triangle,
always think of $a^(2) + b^(2) =c^(2)$ first.

If the third side is not hypotenuse, it is either $a$ or $b$ , and it doesn't matter which one.

let's plug in what we have:
$72^(2) + b^(2) =97^(2)$
$b^(2) =97^(2) - 72^(2)$
$b^(2) =9409 - 5184$
$b = √(9409 - 5184)$
$b = √(4225)$
$b = 65$

Therefore, the third base is 65 cm.

Also, by the way, we know that 97cm is the hypotenus, as hypotenuse is always the longest side in right triangles.

The quotient of a number and ten increased by five

Answers

x/10+5 because it says the quotient which means dividee'd by and a number I use x and then increased by 5 means +5 Hope this helps!=)

"quotient" = answer to a division problem
"increased by" = indicates the operation of addition

Let's allow the variable "n" represent the number. Since we are looking for the quotient of a number and 10, this means we must divide n by 10. Since we are increasing the answer of this expression by 5, we must add 5.

$(n)/(10)+5$
